Here's one if you want to try it. No idea how regularly they show up. Not even that sure how I found mine, or where it is now :?:
I suppose so - the 64k ROM Macs won't take 1.4MB floppies in the first place, will they?
I agree wholeheartedly that this is the most promising starting point:
*emphasis mine
Indeed it opens the way for the various SCSI to xxx storage solutions, including perhaps ordering the ACARD SCSIDE chips and buiding it all on a single board. And given the fact that it uses only two read/write memory locations, and the available source code listing, perhaps it can even be a starting point for a direct flash drive interface.
I was just throwing suggestions out there for anyone who might be interested to follow up on. It's not my place or yours to prescribe or proscribe what "someone" might want to work on, and I apologise if my wording implied any disparagement of this solution.
